5x + 10 = 5(x+2) 6x2 + 12x = 6x(x+2) The only common factor is x+2
I suppose you mean, how do you factor it. 7x2 - 9x - 10 = (7x + 5)(x - 2).
x2-12x+20=0you can factor this equation into:(x-10)(x-2)=0set each factor equal to zero & solve for x to get:x=10 & x=2
If you mean: x^2 +12x +20 then it is (x+2)(x+10) when factored
21x2 + 27x - 30 = 3*(7x2 + 9x - 10) = 3*(7x2 - 5x + 14x - 10) =3*[x*(7x - 5) + 2*(7x - 5)] = 3*(7x - 5)*(x + 2)
(x + 10)(x + 2)
5x + 10 = 5(x+2) 6x2 + 12x = 6x(x+2) The only common factor is x+2

10+12x=-14 -14-10=12x 12x=-24 x=-2
10
x2-12x+20=0you can factor this equation into:(x-10)(x-2)=0set each factor equal to zero & solve for x to get:x=10 & x=2
(7x + 5)(x - 2)
x + 12x + 20 = (x + 10)(x + 2)
3x + 4y + 10 + 12x + y + 1 First, combine like factors: 3x +12x + 4y + y +10 + 1 Add them (or subtract) as necessary: 15x + 5y + 11
The list of choices that you posted with your question doesn't include any factor of that expression.
